I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

The Sensiron SHT45 precision temperature and humidity sensor got featured here a couple of years ago, and wonderful Adafruit ...

How does a silicon temperature (temp) sensor IC actually measure temperature? These ICs take advantage of the basic temperature-dependent behavior of silicon PN junctions. If you have two PN junctions ...
